Why
Duralex glassware is made from tempered soda-lime glass, which is heat-treated to be stronger and more thermal-shock resistant than ordinary glass. In the dishwasher, the high heat (up to 70°C/160°F) and alkaline detergents do not cause clouding, etching, or structural weakening because the glass is non-porous and chemically inert. The manufacturer explicitly states that Duralex products are dishwasher safe. There are no coatings, decals, or seals to degrade. The only potential issue is mechanical chipping if items knock together, so proper loading is advised. No part-specific nuance exists as the entire piece is monolithic glass.
How do you wash Duralex Glassware?
- Rinse immediately after use to remove food residues.
- Place glasses securely on the top rack, spaced apart to avoid contact.
- Use a standard dishwasher detergent (avoid abrasive or lemon-scented varieties if concerned).
- Select a normal or light cycle with a maximum temperature of 70°C (160°F).
- Allow glasses to cool completely before handling to prevent thermal shock.
- Inspect for chips or cracks after washing; discard if damaged.
What happens if you put Duralex Glassware in the dishwasher?
If you put Duralex glassware in the dishwasher, nothing harmful occurs. After one wash, the glass will be clean and unchanged. After repeated washes, the glass remains clear and strong; there is no clouding, etching, or loss of temper. The only risk is physical impact: if glasses clatter against each other or metal items, they may chip or crack. Such damage is mechanical, not chemical, and is immediately visible. The glass does not warp or degrade functionally; it remains safe for use unless chipped. Over many years, some users report a slight surface wear from abrasive detergents, but this is cosmetic and rare.
Frequently asked questions
- Can Duralex glassware go in the microwave?
- Yes, Duralex glassware is microwave safe because the tempered glass can withstand microwave heat without cracking, provided it is not empty and is not subjected to sudden temperature changes.
- Can Duralex glassware go in the freezer?
- Yes, Duralex glassware is freezer safe. The tempered glass can handle freezing temperatures, but avoid extreme thermal shocks like moving directly from freezer to oven.
- What is the maximum temperature Duralex glassware can withstand?
- Duralex glassware can withstand temperatures up to 130°C (266°F) without breaking, making it suitable for hot liquids and oven use up to that limit.
- How should I store Duralex glasses to prevent chipping?
- Store them upright with space between each glass, or use felt separators. Avoid stacking them inside each other as this can cause scratching or chipping.
